ABSTRACT

Objective: To study the anti-fatigue mechanism of Epimedii Folium by network pharmacology. Methods: The main active ingredients of Epimedii Folium and the targets of active ingredients were obtained by TCMSP. The GeneCards was used to predict and screen the anti-fatigue targets. The Cytoscape 3.6.1 software was used to construct the active ingredient-disease-target network. The protein interactions network was constructed using the String database. The GO enrichment and KEGG pathways of the targets were analyzed by using DAVID database. Results: Nine active ingredients were screened from Epimedii Folium, including chrysoeriol, kaempferol, anhydroicaritin, C-homoerythrinan,1,6-didehydro-3,15,16-trimethoxy-,(3.beta.)-, 8-(3-methylbut-2-enyl)-2-phenyl- chromone, luteolin, magnograndiolide, quercetin, 8-isopentenyl-kaempferol, which acted on 31 fatigue targets such as PPARG, GABRA1, CASP3, ICAM1, etc. Biological function analysis showed that the targets of Epimedii Folium included cellular response to hypoxia, regulation of apoptotic, positive regulation of nitric oxide biosynthetic, cellular response to hydrogen peroxide, cellular response to hyperoxia, and negative regulation of lipid storage. Signaling pathway analysis showed that Epimedii Folium exerted the anti-fatigue effect by regulating PI3K-Akt, P53, HIF-1, TNF, FoxO, ErbB, MAPK, and other pathways. Conclusion: This study reflects the characteristics of multi-component, multi-target, and multi-pathway of Epimedii Folium, which provides reference for further research on the mechanism of anti-fatigue effects of Epimedii Folium.

ABSTRACT

Xixiancao( Siegesbeckiae Herba) has the effect of treating ischemic stroke( IS),however,the mechanism has not been fully elucidated. In this study,combined with Lipinski's five principles and Veber oral bioavailability rules,68 chemical components of Xixiancao were obtained by database and literature search. Based on the reverse targeting,248 potential targets were obtained and mapped it to the ischemic stroke target set,47 potential targets for the treatment of ischemic stroke were obtained. Molecular docking technique was used to verify that the Xixiancao component has good binding activity to potential targets. GO enrichment analysis and pathway analysis were performed on potential targets using Clue GO. GO enrichment analysis showed that Xixiancao was mainly involved in life processes such as neuronal apoptosis,cholesterol storage and blood pressure regulation. Pathway analysis showed that Xixiancao may promote vascular repairing and regeneration by regulating the expression of ADAMTS1,FLT1 and KDR in VEGFA-VEGFR2 signaling pathway,activate cell survival signals and inhibit neuronal apoptosis by regulating the expression of CAMK2 AA,MDM2,MAPK1,MAPK3,CDK5 and MAPK10 in brain-derived neurotrophic factor signaling pathway and PI3 K-Akt signaling pathway. Lipid homeostasis and inflammation may also be regulated by Xixiancao through regulating the expression of ESR1,NR1 H3,PPARA,PPARG in the nuclear receptor signaling pathway. In addition,Xixiancao could also prevent platelet aggregation by regulating the expression of ITGA2 B,F2,F10,and ALB,and play an antithrombotic role. The results of this study indicate that Xixiancao plays an important role in the treatment of ischemic stroke mainly through anti-thrombosis,promoting angiogenesis,protecting neurons,anti-inflammatory and regulating blood pressure and lipids.

ABSTRACT

Objective:To analyze the known mechanism of toxicology and predict the unknown toxicity in Asari Radix et Rhizoma sinensis by establishing the network relationship of compound, protein, gene and toxicant reaction. Method:After comparing the Asari Radix et Rhizoma candidate compounds obtained from the traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) database and the toxicological information obtained from the Comparative Toxicogenomics Database(CTD) database, we screened out 13 toxic components from Asari Radix et Rhizoma. And use the Pharm Mapper Server website to find the detailed information of target proteins of the 13 components. The network structure of these 13 chemical components and their corresponding target proteins were drawn by using Cytospace software, and several target proteins with the highest degree of association were found. ClueGO+CluePedia plug-in of Cytospace software was applied in gene ontology(GO) enrichment analysis of genes and kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis, so as to determine the pathways through which toxic substances in Asari Radix et Rhizoma might be harmful to human body. Result:The toxic substances in Asari Radix et Rhizoma may induce tumor and cancer formation through p53 signaling pathway, interleukin(IL)-17 signaling pathway, nuclear factor(NF)-kappa B signaling pathway, tumor necrosis factor(TNF)-signaling pathway. Asari Radix et Rhizoma could inhibit the central nervous system by regulating apoptosis pathways and neurons, and may also cause other autoimmune diseases by IL-17, TNF-α pathway and apoptosis regulation. Conclusion:This study preliminarily explores related mechanisms of toxicity of Asari Radix et Rhizoma,this method can be used to predict toxicity and explain toxicity mechanism of traditional Chinese medicine.

ABSTRACT

Objective To provide theoretical guidance for further research on the role of miR-1 99a-3p in formation and development of bladder cancer.Methods Mature sequence of miR-1 99a-3p was analyzed;target genes and transcription factors of miRNA-1 99a-3p were predicted,and the target genes were analyzed for gene ontology (GO)enrichment and Kyoto Encyclopedia of Genes and Genome (KEGG)pathway.Then TF-miRNA-mRNA network diagram was constructed.Results Sequences of miR-1 99a-3p were highly conserved in various species.In GO analysis,the target genes of miR-1 99a-3p were enriched in many biological processes,such as regulation of cellular process,regulation of macromolecule metabolic process,and regulation of biological process (P <0.01 ).In KEGG pathway,the target genes were mainly located in bacterial invasion pathway of epithelial cells,ECM-receptor interaction pathway,PI3K-Akt signaling pathway,MAPK signaling pathway,small cell lung cancer pathway,and proteoglycans pathway in the cancer (P <0.05).According to the TF-miRNA-mRNA network diagram,the important genes that might be regulated by miR-1 99a-3p were MYC,SP1,mTOR,NFκB,and NFκB1.Conclusion miR-1 99a-3p may directly target mTOR and participate in the formation and development of bladder cancer through regulating PI3K-Akt-mTOR signaling pathway.
